APPARATUS FOR SUPPLYI-NG AIR R OTHER 'JPECIFXCATIQN forming part of Letters .Patent No. 731,376, dated J une 16, i90-3.

Application filed October l, 1900. Serial No. 31,694. illlo model.. l

`a cilizen of the United States, residing at Philadelphia, in the county of Philadelphia and State otPennsylvania, have invented new and useful Improvements in Apparatus for Supplying Air or other Combustion-Supporting Fluid or Substance to Gas or-other Burners, of which the following is a specification.

In an application for Letters Patent tiled by me August G, 1900, Serial No. 26,030, l

show and describe an apparatus for supplying air to gas or other burners for the purpose of increasing the vlighting o1.' heating power thereof. Said apparatus embodies a meten-adapted to be 4operated by the heat from the buzngner and a device or mechanism driven bytne motor for forcing air to the burner, the organization being such that air is supplied to the burner by power deriyed from the burner itself. f

My present'invention relates to improvements upon said apparatus; 'and it consists in certain novel features to be hereinafter described, and particularly pointed out in the claims hereunto annexed.

. lfteferringr to the drawings furnished and forming a part of this specification, Figure 1 is a` vertical longitudinal section ot an apparatus embodying my improvements. Figs. 2, 3, and 4 are enlarged views showing the main working portions of the apparatus in front, rear, and side elevations. Fig. 5 is aview of the blower or air-supplying device with the side cover removed anda portion of the outer casing broken away for disclosing the gas passage to the burner. Fig. 6 is a detail of the motor. Fig. 7 is' a sectional View of the burner employed for igniting the main burner and for initially healing the motor. Figs. S, 9, and l0 are detail views of the cock for con trolling the gassupply.

The apparatus. shown -has been devised for `street or other `lighting purposes and is prorod 5, cast integral with the burner, as clearly shown in Fig. l. rlhe upper edge of the globe 3 is confined or held by a flange at the edge of a conical reflector T, arranged above the burner and suspended by hangers S from a heat-insulator il, to be hereinafter `referred to.v i

As heretofore indicated, my apparatus embodies as an essential feature a motor adapted to be operated bythe heat from the burner to which air is to be supplied. The motor shown by me is a well-known type ot' caloric engine, in which air is expanded and con- COlllRllSTlGN-SUPPORTlNG FLUlD 0R SUBSTANCR l0 GAS DR OTHER BURNERS.

tracted for furnishing the motive power by beiug'alternately shifted from one end tothe.

other of a cylinder whoseends are maintained at widely-different temperatures. Said engine will need no detail description as to its operation and will be described only as far as may be necessary to give a proper underl .flange ll, 4which is'tightly clamped between a clamping-ring 1:2 and a casting 13, the lat- Vter closing the upper end of the cylinder, as

shown in Fig. n'. "The motorcylinder l-i is cast integral with the casting 13, and at the bottom of said cylinder there is an air-passage l5 through tile casting to the cylinder l0. The motor-shaft lG is supported in a bearing i7, cast integral with a casting 1S, forming the main walls ot' the air-supplying device andsecured tothe casting 13 by screws 10, though these parts 13 and 18 maybe made in one casting, if desired. a crank 20, which is connected by link 2l and rod 22 to the air-displacer in the cylinder 1D, said rod being guided by a hollow post El, formingr a part ot' casting i3 -ihe piston ofcylinder li connected by pitinan 2G with .a notched or toothed crank-wheel 2? at the .opposite end of shaft lo', said wheel being vast At one end olf-shaft .'lGis4 ing with the burner l.

lpipe 38.

integral with a fly-wheel 28, also serving' es it belt-wheel for driving the blower ot" the nir? 'ing 32 for-the 'admission of stir to the blower,

its shown in Fig. 3. The blower 29 is :t Series of fons 33, tongentiiilly arranged on e sheit 34, mounted in n. bearintr in the casting 18, the entire set of fetus beingr formed from a. single piece of sheet nicht! cut and bent clearly illustrated in Fig'. 5. Attached to sheftft upon the outside of the blower-chnm ber is a pulley 35, which is connected by n belt 36 with the fly-wheel 2S of the motor. The blower-chamber is provided with en niroutlet 37, communicating,r wim n pipe 38, tapped into the casting 18 and communicat Around n. portion et' the periphery or outer edge of cestino' 18 is e. ges duct or paeeege 33, lending from the mitin gas-supply pipe 40, which is tapped into the upper portion of the casting to the opening 37, connecting the blower-chamber with the Pipe 40 ie to be attached to n service pipe anti is provided with e. two-wey cock 4l for controlling tho supply of ges to fthe burner l and also to e pilot :enti heating burner`42, to be hereinafter referred. to.

It ie now to be understood thi-it when heet is applied to the lower end ot' cylinder i0 the expansion'of oir therein will censo piston. 25 to rise for rotating shaft 1G, enti the letter will operate through the displnccr 23 to shift the air from the bottoni to the top of the cylinder, where it will contract, because ot the diierence in temperature nt that end ot the cylinder, to permit enti niti in the descent of the piston 25. The descent. of pieton 25 causes the air to be displaced from the cool lo the hot end of the cylinder l0, when expan- `sion again takes place its before, the motor beingr thus kept in continuous operation.

The blower29 should be revolved at :t in uch higher rate offspeetl than cer. be attained by the motor, intl while gearing mny be relied upon as the con n'ecting menus I have adopted :i belt and pulley ztsfheingr much simpler noti less liable to require attention; but it inlportant where it belt is'used to provide :in automatic belt-tightener to compensate for variations in the belt duc to variations in temperature. In the apparatus shown provide n gravity be]t-tightener.consieting'o :t roller 43, mount'etl on the end of :in nrm Lt-i, which ie pivot-illy mounted on the casting 18 und weighted7 as :it 45, for causing the roller t0 bear upon the beit with constant pressure sufficient to compensate forvariiitions in the belt or in other portions ot the apparatus.

The revolution of the blower causes nir to be forced into the' pipe 38, leading to the burner l, Said :tir being mixed with the irais also entering said pipe from the pipe l i0 through the passage 3. riho pressure and cylinder l0, es will be explained.

quantity of tir :supplied to the burner is regulated bythe qnitntitjypermitted to enter the blowercheinber, this being regulated by :t slide or demper lli, controlling; the opening; or nii-niet 32, Qrovitletl in the detachable cover 31, as illnetreteti in Fig. 3.

Adjacent to thebottoin oi cylinder 'tO there ie :t burner 2, that performs Service its e pilot-` burner for ignitingr the mein burner'l and also :te e. burner for initiellyhenting the cylinder l0 prepnrrttory 'to starting,r the apparatus. Said burner is et the end or" si 'tube 27, con nectet to the two-way cock 4l, and in scid tube, neer ite lower enti, there is an opening 48 (see Fig. for the admission of air, which is drawn into the tube by the ges when the letter is supplied under sufficient pressure. A small quantity of gan is continuously snpplied to the tube et? through zt bypass 49 in the cock 1li, the quantity being; reguleteti by t screw 50. (Shown in Figs. 8, Q, enti 10.) The gne thus7 permitted to pese to the burner is kept continuously burning Afor igniting the mein burner l :intl cleo for heating the y As shown in Fig. 8, the plug 5l ot cock Il is provided with e main gnepnsenge tml it branch peesege 53, which are both closed to the passage of gas when the plug is turned in the position indicated in eeitl re. v*l/*lieti the plug is turned to the Veit-ion shown in Fie'. i?, ges entere tnhc ut7' unifier full presso re, :intl burner 42 then nets ne :t 'lunsen burner for heating.; cylinder l0, :tir being drawn to the 'burner through the openingY 48 in tube 47, as already explained.

can be set in motion. For this purpose l have devised. starting.,r mechanism, consisting' prt an arm 59, pivoted at one end, as at 90, to a second arm lil, wl'iich'latter is itself pivoted to a stud 62 on the lcasting 1S, as shown in Fig. 2. Arin 59 is provided with teeth G3, which engage the teeth on the crank-wheel 27 and start the motor, as will presently appear. The free end of arin 59 is attached to and supported by a chain 64, which passes through a second hole in the guide 57 and which is attached tothe chain 54 at G5, as shownin Fig. 4. Arm 59 is held in its normal or rearward position by a spring` 66, attached` to arur 6l, and by its own weight it rests slightly below the position it first When chain 54 is pulled for opening the cock 4l and converting the pilot-burner into a Bunsen burner, chain vG4, being attached thereto, is also pulled; but as the pull is slight arm 59 is not moved forward sufficiently tostart the motor and is quickly returned to its nor-l mal position by the spring'ti, acting on arm 61. `After cylinder 10 has been heated chain 54 is pulled for turning on gas to the main burner, and this being done With a strong quick motion chain 64 first raises and then pulls aru1.59 quickly across the periphery of wheel 27, the teeth on thearm engaging the teeth on the Wheel and turning it for starting the motpr, as will be readily understood. lVhen the. chain is released, arin 59 drops away from wheel 27 and is returned to its original position without contact with wheel 27 and may again be pulled forward in the same manner without disturbing cock 4l, which remains open until closed by a pull on the chain 55.

The motor being located above the burner l, it is importantlthat provision be u iade for insuring a proper difference in temperatures between the two ends of cylinder l0, as well as to prevent products of combustion from entering the blower-chamber. For this purI pose I have provided a heat-insulator 9, which surrounds the lower end of cylinder 19, as shown in Fig. l. Said insulator consists of a series of diaphragme 68 68 and 69,'sepa. rated from each other .by ventilated spaces 70 and lpreferably made in 4progressive sir/:es and arranged so that lthe'largest will project over and beyond the edge oi theorie next underlying it and the latter project beyond the next underlying,l it, and so ou to the smallest, which is placed at" the bottoni or The diaphragme (3S G8, of which there may be any number,'arc composed of asbestos oizother heat-insulat ing material and are supported by a dish' shaped casting` G7', provided with openings 'Jl for alordingr free circulation et air be tween the diaphragme. Cast-inn' G7 is also provided with a sleeve 72, by means of which it is secured lo the pipe 3S by asiat-screw, as clearly shown. The upper diaphragm G9 is comp sed ,ot sheet lmetal and made conical in form, with its outer edge bent downwardly to lit over the edgefcf the casting 67, said diaphragm thus serving as a cover for said casting. The conical reflector 7 serves also to direct heat from the burner to the exposed end of cylinder lO through the opening 73.

For oiling the bearings and movable parts of the' apparatus l provide a single oil-cup 7 4, from which the parts requiring oil are 'fed by wicks supported in tubes 75, the entire appa ratus being thus kept in good ruiming order, with necessary attention 4reduced to a miniinuzn. I

The entire apparatus above the `insulator 9 is inclo'sed within a case or cover consisting ot two sheet-metal cylinders of dilerent diarneters, 76 and 77, and a conical cover 78. The smaller cylinder 76 is secured to the insulator 9 by angle-irons 79 and raised slightly above the saine to afford a Ventilating-space 80. The larger cylinder 77 issecured to the upper endof cylinder 76 byirons 81, the space 82' between the two cylinders aloiding an additional Ventilating-space and also as the opening through which the operating or controlling chains 54 and 55 pass to the outside of the casing. The conical cover 78 is secured to the pipe 40, and at its outer edge it is provided with a flange 83, which overhangs the upper edge of cylinder 76 in such a manner as to afford a Ventilating-space S4, as clearly shown. i

For affording a proper circulation of air through the casing to keep the upper portion of the apparatus as cool as possible I have converted the ilywheel of the motor into a rotary fan by attaching thereto blades 85, which are secured to the spokes of the wheel and set at a slight angle, as will be readily understood; but of course a fan constructed separately from the motor and driven. thereby may be employed, if desired.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-` A l. in an apparatus of the character ldescribed, a burner, a motor operated by the heat from said burner, a device or mechanism driven by said in'otor for supplying air to said burner, means for controlling,r the t'uelsupply to theburner, mechanism for initially starting the motor, and operating connections between said means and starting mechanism, substantially as described.
